Patent CA-2134731-A1 (CA)
Inventor: LINDGREN PER-OLOV
IPC: H01M6/52
Filed: 1994-10-31
Abstract: A method for dealing with mercury-containing waste including button-type batteries, wherein the waste is heated in a furnace while being agitated and in the presence of elementary selenium vapour in an amount sufficient to form mercury-selenide from essentially all the mercury contained by the waste. The waste is heated to a temperature at which mercury and selenium will be present in a gaseous state and at which solid mercury-selenide will not form, and a partial pressure of oxygen is maintained at a sufficiently low level to avoid oxidation of the selenium. The thus treated mercury-freed waste is extracted from the resultant process gas and from any other solid material that may be present and is either dumped or worked-up metallurgically. After the waste has been extracted from the process gas, the process gas is cooled to extract therefrom solid, stable mercury-selenide dust suitable for dumping, whereafter the gas is passed through a filter with the intention of extracting any gaseous mercury that may remain in the gas, whereafter the thus cleansed gas is released to atmosphere. The invention also relates to plant for dealing with mercury-containing waste. <IMAGE>

Title: Buffer management policy for an on-demand video server
Inventor: DAN ASIT
IPC: H04N7/173
Filed: 1995-02-13
Abstract: A method for reducing the disk bandwidth capacity required by a multimedia server by selectively retaining blocks that have already been read in by one stream for re-use by another. Due to stream-dependent block buffering, the storage requirement is less than that for whole-movie buffering and because the policy is dynamic, it also adapts rapidly to changing access patterns.

Title: Distributed database architecture and distributed database management system for open network evolution
Inventor: OULID-AISSA MOURAD
IPC: G06F17/30
Filed: 1995-03-28
Abstract: Abstract of the Disclosure A distributed database management (DDBMS) system for switching applications that combines rapid feature deployment with high real-time performance. The system architecture encompasses a new software boundary between application and database, yet provides the benefits of open standard interfaces and distributed transaction control. To accomplish this dichotomy, an object-oriented schema is used to arrange the DDBMS as an intelligent service provider, separating services from physical location and implementation. A software containment approach is utilized to optimize interfaces based on grouping of data so as to permit application-specific routines to be "plugged-into" the database. The DDBMS is arranged to address extendibility and real-time performance needs of capabilities such as ISDN and IN is switching offices and network nodes.

Patent CA-2152061-A1 (CA)
Inventor: MAKOWER JOSHUA
IPC: A61B19/00
Filed: 1993-12-07
Abstract: A device for measuring the depth below skin level of a blood vessel that has been punctured in the course of a catheterization or other interventional vascular procedure comprises a tubular member (18) having a proximal end (20) and a distal end (22) portion that is preferably tapered to a small outer diameter. The lumen (24, 26) may have a stepped diameter extending between the proximal and distal ends (20) 22). A first portion of the lumen (26) is distally located and is of a diameter generally equal to the diameter of a guidewire with which the measuring device is used. The second segment of the lumen (24) is of a substantially larger diameter. A side entry port (32) is made through the wall of the tubular member (18) at the distal base of the larger diameter section of the lumen (24). Graduated markings on the side wall of the tubular member (18) extend from the side entry port (32) toward the proximal end (20) of the instrument. When the instrument is fed over a guidewire into a puncture wound formed through the skin and into an artery, the wall of the artery can be accurately located rolative to the skin's surface by noting the graduated markings on the exterior of the tube (18) at the point where blood flow enters the side entry port (32) and fills die larger diameter lumen (24).  Rather than having two coaxially disposed lumens as above, the tubular member may have a double lumen (32, 40), one extending the entire length for accommodating the guidewire and the other extending between the tube's proximal end and the side entry port (42).

Title: Offset Transmission Line Coupler for Radio Frequency Signal Amplifiers
Inventor: NAGODE THOMAS D
IPC: H01P5/18
Filed: 1994-10-03
Abstract: An offset transmission line coupler (115) for a transmitter output signal (123) generated by an RF signal amplifier (103) includes a through-path transmission line (201) and a coupled-path transmission line (202) electromagnetically coupled thereto by multiple serpentine-like portions (such as portions 641, 642, 643 and 644 in Fig. 6), which are disposed on opposite sides of the through-path transmission line (201) for enhancing coupling sensitivity and eliminating degradation in the amount of coupling due to variations in the transmission line plating registration. Offset portions (641, 643) on one side of the through-path transmission line (201) provide substantially the same amount of coupling as the offset portions (642, 643) on the other side of the through-path transmission line (201). The offset portions (641, 642, 643, 644) are offset substantially the same distance from the through-path transmission line (201), and the total length of the offset portions (641, 644) on one side are equal to the total length of the offset portions (642, 643) on the other side of the through-path transmission line (201).

Inventor: HENRY RAY
IPC: H04J3/16
Filed: 1994-11-01
Abstract: A method and system for locating control channels (70), particularly digital control channels are described. By grouping the channels which are candidates for carrying supervisory messages in blocks indicative of their relative likehood for being used as control channels, a mobile station can begin its search for a control channel with channels which are most likely to actually be control channels. Placing location information on other channels allows the mobile station (120) to be redirected to a control channel when it reads one of these other channels. Similarly, by placing information describing the location of a control channel in a message associated with handoff, a mobile station avoids the necessity of having to relocate a new control channel associated with the base station to which the mobile has been handed off.

IPC: A61K31/138
Filed: 1994-02-17
Abstract: The in vivo chemotherapeutic treatment of cancer cells in a living animal is improved by first administering to the animal, a compound which inhibits normal cell proliferation while promoting malignant cell proliferation, specifically a potent antagonist selective for intracellular histamine receptors, in an amount sufficient to inhibit the binding of intracellular histamine to the receptors in normal and malignant cells.  An enhanced toxic effect on the cancer cells from the chemotherapeutic agent is obtained while any adverse effect of the chemotherapeutic agent on normal cells, particularly bone marrow and gastro-intestinal cells, is inhibited. Certain fluoro derivatives useful in such procedure are novel compounds.

The first layer (28) index n2 causes light input (22) through the back surface (20) of the layer to be preferentially outputted in the first layer. A second layer (30) is coupled to the bottom of (16) of the first layer (28) and selectively causes output of light into ambient. Additionally layers such as an air gap (31), can be provided adjacent to the wedge shaped layer. The wedge shaped layer can also have a variable index of refraction n (x, y, z).

Title: Laser scanning system and scanning method for scanning bar codes
Inventor: DVORKIS PAUL
IPC: G06K7/14
Filed: 1995-10-25
Abstract: A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional or two-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edges of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.
